Do investors care about noise trader risk?
The link between investor sentiment and asset valuation is at the centre of a long-running debate in behavioral finance. Using a new composite sentiment indicator, we show that the conventional risk does not explain the abnormal returns of portfolios most sensitive to the sentiment factor. Our result supports the existence of a sentiment risk valued by financial markets. We also find that the firms more impacted by the sentiment risk correspond to difficult to arbitrage and hard to value stocks, e.g. small stocks, growth stocks, young stocks, unprofitable stocks, lower dividend-paying stocks, intangible stocks and high volatility stocks.
